ROTARY MOTOR.

Specification of Letters Patent.

Application filed January 18, 1912. Serial No. 672,009.

To all whom it may concern: r

Be it-known that I, ELMER E. HAUER, a citizen of the United States,residing at Stateof Ohio, have invented certain newand usefulImprovements in Rotary Motors," of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to rotary motors and more particularly to a motorof this type adapted to drive boiler tube cleaners, although it may beused for other purposes.

The object of my invention is to provide a compact and eiilcient'motorthe parts of renewal and repairs. i

A further object is to provide improved bearings to carry the rotaryinotor member.

WVith these and other objects in view my forth in the claims.

In the drawings Figure 1 is a 1ongitudinal section'of a motor embodyingmy in.- vention, said section being takenon'the line 11 of Fig. Fig. 2is a like section taken on the line 2-2 of Fig. 3. Figs. 8 and 5 arecross-sections on the lines 3 3 and 55 respectively of Fig. 1 and Fig. 4is a front Like numerals represent the same parts in the several news. I

In the drawings 1 represents a motor cyl- 2 forming an abutment. Atwo-part casing 23 having heads at its outer ends extends over and isscrew-threaded to said cylinder with its inner ends tightened againstsaid abutment.

In thepresent instance I have shown the motor cylinder forming a chamberof such dimensions that when the rotary motor with the walls of thechamber in two places opposite each other forming two oppositelydisposed chambers 5 and 6 as particularly shown in Fig. 3. Piston blades7 are seated in recesses 8 of the rotary member and are adapted to moveradially into the chambers 5 and 6 in a well known manner.

A disk or partition 9 seated in one part portion 10 which extends intoan axial recess 11 of the rotary motor member and forms a bearing tocarry the rear end of said member. Said rotary motor member is providedwith a forwardly extending portion or shaft.12 journaled in an openingthrough the head of the other portion of said casing, said opening beingpreferably provided with a bushing 13; and said projecting portion orshaft is screw-threaded at 14 to attach the tool to be driven. A wearingplate or ring 15is interposed between the rotary motor member and thefront head of the casing. The Tear head of the casing is provided withan opening in which a supply hose 16 is secured by segments 17 held byscrews 18 as particularly shown in Fig. 5.

The motive agent is admittedto the chambers 5 and 6 through inlet ports19 extending from the axial recess 11 through the rotary motor memberand open in the rear tion 10 adapted to register with the ports 19 inthe rotary motor member, said proj ection 10 having transverse slots 22through which the ports 21 open to the ports 19 as particularly shown inF 3. These ports are held in proper relation to each other by screws 99and the disk or partition is re-v tained in place by said screws whenthe rear part of the casing 3 is removed.

The front head of the casing is provided with segmental openings 241 toreceive an discharge the exhaust from ports 25 in the plate or ring 15;and a dowel-pin 26 holds said ports in proper relation.

The constructions shown but not claimed herein are claimed in myapplication Serial Number 666,517, filed Dec. 18, 1911. 7

Having thus described my invention I claim v 1. In a rotary motor, acasing having a supply head at its rear end and an exhaust head at itsfront end, a disk or partition having a stationary forwardly extendingprojection secured in front of said supply head, a rotary motor memberhaving an axial recess into which said projection extends and forms a:bearing therefor, said rotary motor member also having a for wardlyextending shaft journaled in and projecting through an opening in saidexto be driven.

2. In arotary motor, a casing havingoppositely disposed supply andexhaust heads, a disk or partition having arstationary projectionextending therefrom with ports therethrough secured in front of saidsupply head, a rotary motor member having an axial recess into whichsaid projection extends forming a bearing therefor, said rotary motormember also having ports adapted to register with the ports in saidprojection and a forwardly projecting shaft journaled in and extendingthrough an opening in the exhaust head and adapted to attach the tooltobe' driven.

3. ma rotary motor, a motor cylinder having an abutment, a rotarymotormemher, a two-part casing having heads atits' outer ends, securedover said cylinder against said abutment, said rotary motor memberhavlng a pro ect1on 10urnaled in an opening 1n one of said heads, theother motor member.

In testimony lwhereof I have hereunto affixed my signature in thepresence of two witnesses.
